我正在开发一个 django 项目，该项目将用作 webhook 的端点。 webhook 会将一些 JSON 数据发布到我的端点，然后它将解析该数据。我正在尝试为它编写单元测试，但我不确定我是否正确发送了 JSON。

我在 pipeline_endpoint 中不断收到“TypeError:字符串索引必须是整数”

代码如下:

# tests.py
from django.test import TestCase
from django.test.client import Client
import simplejson

class TestPipeline(TestCase):

    def setUp(self):
        """initialize the Django test client"""
        self.c = Client()

    def test_200(self):
        json_string = u'{"1": {"guid": "8a40135230f21bdb0130f21c255c0007", "portalId": 999, "email": "fake@email"}}'
        json_data = simplejson.loads(json_string)
        self.response = self.c.post('/pipeline-endpoint', json_data, content_type="application/json")
        self.assertEqual(self.response.status_code, "200")

和

# views.py
from pipeline.prospect import Prospect
import simplejson

def pipeline_endpoint(request):

    #get the data from the json object that came in
    prospects_json = simplejson.loads(request.raw_post_data)
    for p in prospects_json:
        prospect = {
            'email'          : p['email'],
            'hs_id'          : p['guid'],
            'portal'         : p['portalId'],
        }

编辑:整个回溯。

最佳答案

@mrmagooey 是对的

def test_your_test(self):
    python_dict = {
        "1": {
            "guid": "8a40135230f21bdb0130f21c255c0007",
            "portalId": 999,
            "email": "fake@email"
        }
    }
    response = self.client.post('/pipeline-endpoint/',
                                json.dumps(python_dict),
                                content_type="application/json")

使用 json.dumps 而不是 json.loads
